ELectric Fans on a Cummins ?
For $600 or so FLex a lite makes a fan kit for the CUmmins 5.9 Anybody using it? is there a noticable MPG gain running empty? Does it work well enough to cool the truck when loaded?

As previously posted 1 hp equals 746 watts. 746 watts at 12v equals 62 amps. A fan using 10 hp needs 620 amps. Do the math. Try and find cables big enough to handle the amperage. Even if you can make more hp, more hp means more heat which means even more cooling required.
There's a reason they don't put electric fans on these things.
How did you get to 10 hp? THe fans draw 60 amps- so 1 hp.
THere are a lot of reasons they don't put electric fans on these things, but one upon a time they only put them on FWD rat poxes and now they try to put them on EVERYTHING. I think it will meet my needs and save me 2 mpg in my daily drive.
People re-engineer their trucks for performance, noise, or just to look ridiculous and everyone thinks that cool. I'm more interested in re-engineering for efficiency.
Flexalite claims up to 27 hp gain over stock. I thought I was being conservative. That tells me there is no way electric fans will move as much air when the going gets tough. Daily driving sure but not for towing heavy thank you.
